I work inside the core/elevator shaft of commercial highrises, it is concrete construction 500 ft in the air. You would learn how commericail hisghrise buildings are built from the inside out. You will be filthy by the end of the day, covered in dirt, concrete, sweat, grease and form oil. No way around it.! This is a fast paced job, you would learn to climb rebar columns. a very fun job!!! 100% fall protection all safety prcautions taken. please contact. Mitchell @ 360-829-7153 p.s. Seattle is beautiful in the summer!
